Check out these guys at Coastal Alloy Rim Repair | Remove Ugly Scratches - From $99 they did two of my 20" Suzuka wheel from a pothole. They were really bad and thought I had to get new wheels from VW but at the cost $1500 each, no thanks!!! Anyway Coastal Alloy came out within 2 days, price was $220 as one wheel was really bad and all done within 90 minutes. These guys did a fantastic job and honestly I can not tell where the gutter rash was unless you inspect it really close to spot the machine rings from the manufacturer.
Would highly recommend them.
